SHUTTLE-CHANGING MECHANISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 616,234, dated December 20, 1898-.

Application filed Mar h 31, 1897.

To all whom it mag concern.-

Be it known that I, EDUARD HERZIG, a resident of West IIoboken, county of Hudson, State of New Jersey, have invented certain new and useful Improvements in Shuttle- Ohanging Mechanism forLooms, of which the following is a specification.

My invention relates to shuttle-changing mechanism for looms, and has for its object to produce a device by whose agency a spent or empty shuttle may be replaced by a full one when desired.

To this end my invention consists in the construction of shuttle-changer hereinafter set forth andclaimed.

In the drawings, Figure 1 is a front elevation of a loom which, however, forms no part of my invention, but which shows a shuttle changer embodying my invention in a position in which it may be used. Fig. 2 is a section through Fig. 1 on line 2 2 thereof, exhibiting clearly the position of the shuttlechanger on the batten. Fig. 3 is a front elevation of a portion of the batten carrying the shuttle-changing device. Fig. 4 is a rear elevation of the same. Fig. 5 is a section on line 5 5 of Fig. 3, showing the shuttle-changing device in plan. Fig. 6 is a section on line 6 6 of Fig. 3. Fig. '7 is a plan view of the shuttlecarrier, showing the shuttle engaged therewith. Fig. 8 is a front view of the shuttlecarrier. Fig. 9 is a rear View of the shuttle, and Fig. 10 is a section through the shuttle and shuttle-carrier on line 10 10 of Fig. 7.

Referring particularly to Figs. 1 and 2, A is the framework of the loom, carrying the usual beams B and take-up beam 0 and provided with a batten D, suspended at E and operated by the batten-Working mechanism F. The loom is also provided with the usual healds G, as will be well understood. The loom is also provided with the usual shuttleboxes H, carried by the batten. The batten D is formed with two ways d, constituting the shuttle-raceway and between which ways a grooved shuttle-carrier 6 travels. This shuttle-carrier e is shown as having a plane rear face. (See Figs. 4, 6, and 7.) Any suitable shuttle-driving mechanism may be employed. In the drawings I have shown the shuttles as provided with teeth at, (see Figs. 6 and 10,)

Serial No. 630,043. (No model.)

which mesh with suitably-driven pinions m on the batten, (see Figs. 1, 8, and 6,) whereby the shuttles are driven. In the drawings the wheels w are shown as driven by an oscillating rack m driven by a driven pinion 50 (See Figs. 1 and 3.) The shuttle-carrier is also provided upon its front face with a plurality of vertical guides e 6 (see Figs. 7 and 8,) which are provided at their lower ends with inturned lugs 6 6 which lugs are adapted to receive the impact of latches on the shuttle, as will be described. I

Between the lugs e etand the side faces e e of the Ways or guides e e a space 2 is pro vided, which space 6 allows the latches of the shuttle to pass freely through when the said latches have been pressed apart, as will be explained. The shuttle-carrier is likewise provided with a cam e and with springsre Fig. 8, which'serve to enter slots f in the shuttle f. (See Fig. 9.) The shuttle f is pointed at both ends, as usual, and is provided upon its top with a curved spring f whose ends f project downward through apertures f in the shuttle and terminate with outwardly-turned latches f which are adapted to reach contact with the lugs e e of the shuttle-carrier, as clearly shown in Fig. 10.

Pressing downward upon the bulged portion of the spring f will have the effect of spreading its ends apart, thereby swingingthe latches f laterally in the slots f of the rear wall of the shuttle and moving the said latches over the spaces 6 between the lugs e e and the side walls 6 e of the guides e e of the shuttle-carrier, so that the shuttle which is supported mainly by the said latches restingagainst the said lugs will now be free to be driven downward, the said latches having been moved oif the said lugs and the shuttle being now supported wholly by the springs e", entering the slots f f of the shuttle. 1 It will thus be evident that a sharp blow delivered upon the spring f will have the effect of releasing the shuttle from the supports in the shuttle-carrier and driving the same downward. The mechanism for effecting this operation is best shown in Figs. 3, 4; 5, and 6. In these figures a pair of standards 9 g are shown rising from the lower rail or way d, mounted ICO on the batten D and secured to the upper rail (Z and joined at their top by a cross-piece g, to which they are secured. An upright slide g (shown in.elevation in Figs. 4L and 6 and in section in Fig. 5) slides freely up and down in these standards 9. This slide terminates at its upper end in a head 9 which extends toward the front of the shuttle-changer and is provided at the said front with a downwardly-projecting follower g which may be shod on the bottom with felt 9 Fig. 3, and is provided in the rear with a rib 9 Two brackets h h are mounted upon the upper rail (1 of the shuttle way and are provided with outwardly-projecting guides 7L2, which are provided with inwardlyprojecting lugs 71., which lugs are adapted to receive the latches f of the shuttles f. Between the lugs 7i and the side walls of the ways spaces h are provided, through which the latches f 5 of the shuttle may pass when the said latches are spread apart by pressing on the spring f of the shuttle, so that the lugs 71 serve to support the idle shuttle above the raceway until it is desired to bring it into action. The guides for the shuttle are likewise provided with leaf-springs h (see Figs. 3 and 6,) which may bear against the rear face of the idle shuttle. The slide g is provided at the rear with a cross-head g (see Figs. 4, 5, and 6,) which cross-head is provided with a shoe or guide 9 hung loosely upon the pin 9 and pressed outward by the spring g seated in the cross-head. This shoe or guide g embraces a rod 9 working in guides Q12, the rod being surrounded by a spiral spring g which is secured to the rod at and to the batten at 9 The rod g bears at its upper end against the cross-head 9 the spring serving to raise the said rod and cross-head to restore the parts to position. Mounted also upon the batten is a pivoted latclrlever a. (Shown in front View in Fig. 3, in plan view in Fig. 5, and in side View in Fig. 6.) This latch-lever is pivoted intermediate of its ends and is provided at its upper end with a stop a, projecting to the front, and a lug a projecting to the rear. This lug a is flat-faced and rests at either extremity of the swing of the lever upon a flat leaf-spring (L4, (best shown in Figs. 3 and 6,) which leaf-spring serves to hold the latch in its vertical position, except when it is swung aside by the cam e on the shuttle-carrier. At its lower end the lever a is provided with a toe M, which projects into the path of the cam 6 which is carried on the shuttle-carrier. its vertical position-that is to say, when the shuttle-carrier is not immediately under it the stop a will be in the path of the rib g on the follower g, so that the head g and its follower cannot be driven downward. When,

however, the sh uttle-carrier is in the positions shown in the figures, the cam e will swing the lever to aside, so as to remove the stop a from the path of the rib g.

The batten may When the lever a is in also be provided with a wall D, which forms with the batten a trough for the reception of the shuttle when it is driven out of the shuttle-carrier.

Having described the construction of the device shown in the drawings, I will now pro ceed to describe the operation thereof.

It will be understood that in the normal operation of the loom a shuttle is carried by the shuttle-carrier, as shown in Figs. 7 and 10, the latches f of the shuttle resting upon the lugs e a of the shuttle-carrier. This sh uttlecarrier vibrates rapidly back and forth across the batten in the ways or guides (l, laying the thread, the batten of course beating up after each shot. Meantime the idle shuttle is rest ing in the guides 71?, the latohesf of the said shuttle resting on the lugs h of the said guides, thus supporting the said idle shuttle clear of the active or working shuttle. The follower g is in such position as to come against the spring f of the idle shuttle. Now

as the working shuttle oscillates back and forth in the raceway the cam 6 will at each shot strike the toe a of the pivoted lever a and swing it; but as long as the said lever a is in a vertical position the head g with its follower g and guide g cannot be driven downward. -When, however, it is desired to change the sh uttles-that is to say, to remove the working shuttle from the shuttle-carrier and to replace it with the idle shuttle, which then becomes the working sh uttle-the working shuttle is brought to the position shown in the drawings, where it is immediately under the guides carrying the idle shuttle, in which position the cam a will swing the lever a into the position exhibited in Fig. 3, so that it will not impede the downward movement'of the head g \Vhen the parts have comeinto this position, a sharp blow is dealt to the head g which produces the following effects: The follower g is brought against the spring f of the upper or inactive shuttle, which, as before explained, will have the effect of spreading the ends of the said spring, thereby moving the latches f from contact with the lugs 7L3 on the guides 72 so that as the follower g continues to descend it will carry with it the upper shuttle, which, coming against the spring f of the working shuttle f, presses I down upon the said spring, thereby spreading its ends, thus moving the latches f off the lugs c e of the carrier, thereby freeing the said working shuttle from its supports and driving the same into the trough of the batten and by the impact springing the idle shuttle into the shuttle-carrier, where its latches f will come against the lugs e e of the sh uttlecarrier and hold the said shuttle supported in the shuttle-carrier, which shuttle now becom es the working shuttle and may be carried back and forth by the shuttle-carrier. The head g and its adj unctive mechanism are raised by the spring g and another idle shuttle placed in the guides 7L2.
